3.3V、1.2A、6MHz 微型降压直流/直流转换器

The LM3281 is a high-efficiency low-noise miniature DC-DC converter optimizedfor powering noise-sensitive wireless connectivity chipsets and RF Front EndModules (FEMs) from a single Lithium-Ion cell. The LM3281 is ideal for “alwayson” applications with very low unloaded quiescent current of 16 µA (t • Operates from a Single Li-Ion Cell (3 V to 5.5 V)\n• 6-MHz (typ.)
